RUBBER TYPE.

Specification of Letters Patent.

Patented Mar. 14:, 1916.

Application filed June 13, 1912. Serial No. 703,372.

To all whom it may concern:

Be it known that 1, MARCUS O. ANTHONY, a citizen of. the United States,residing in the city of New York, borough of Manhattan, county and Stateof New York, have invented a certain new and useful Rubber Type, ofwhich the following is a specification.

This invention is an improvement in rubber type.

Numerous forms of rubber type have heretofore been used, but, so far asI am aware, they all have certain disadvantages of which it is theaim ofthe present invention to overcome. For example, the commonly used rubbertype band with integral printing characters becomes permanentlystretched after it has been used a short time, with the result that itis impossible to accurately print therefrom. In order to obviate theobjection due to permanent stretching, it has been proposed to mount therubber type on a rigid backing, such as a metal plate or a fabric. Thesestructures, however, also possess certain inherent disadvantages.

The present invention embodies rubber type, preferably in the form of aband, vulcanized or similarly secured to a fabric and intermediate whichtype and fabric is a perforated thin metallic band. This results in astructure which is inelastic yet flexible and particularly durable.

In the accompanying drawings, I have illustrated one practicalembodiment of the invention,.but the construction shown therein, is tobe understood as illustrative, only, and not as defining the limits ofthe invention.

Figure 1 is a vertical section, partly in elevation, illustrating thepresent invention in connection with a particular form of printingdevice. Fig. 2 is a plan view on an enlarged scale of a part of therubber type, illustrating the layers of rubber,

metal and fabric partly broken away and metal is interposed between thelayers A, G of rubber and fabric, respectively, and this intermediateflexible layer B is provided with a number of perforations I) throughwhich is adapted to extend some of the rubber composing layer A, therebyforming the tongues Z) whichunite rubber layer A to backing O, theresult being to substantially incase the flexible metal layer B by therubber and fabric layers A, U, respectively.

Layer A is composed of any suitable kind of rubber or rubber compound,and this layer is provided with type characters a integral therewith,said type characters being molded or otherwise formed on the surface ofthe rubber layer. Obviously, the type characters may be of any form, butas shown in Fig. 2, the type characters are numerals arranged in rows.

The backing'C is composed, preferably, of textile fabric, but any otherflexible material may be used as a backing layer; for example thebacking may be composed of rubber. but experience shows that fabric isprobably the most suitable material for the purposes of the invention.

The several layers formed and arranged as described constitute what maybe referred to as a composite fabric. wherein the front layer and thebacking layer are intimately united with the interposed flexible metallayer. The composite fabric is preferably used in the form of asubstantially endless band, as shown in Fig. 1, said composite fabricbeing formed into a loop, and the end portions of said fabric united inany suitable or desirable way, so as to result in the endless band.

Obviously, the fabric may be of any desired width and length, and ifdesired the fabric may be quite narrow so as to contain a single row offigures, or it may be wide enough to contain two or more rows offigures, or it may be wide enough to carry the names of the months inthe year or the days of the week. Manifestly, any desired data may beprovided on the endless band to serve the purposes for which the band isintended. As disclosed in Fig. 1, two endless bands are emploved in aprinting device of the character disclosed in a prior application filedon December 80th, 1911, b Marcus 0. Anthony and Bernhard H. F lurscheim,Serial No. 668,609. As therein shown and described, the printing device14, 15, which carry rollers or wheels 16,

17, respectively. Around the roller 16 fits an endless band 18 whichpasses below the guide 12. Cooperating with the other roller 17 is anendless band 19 passing below the guide 13. As shown, guide 12 isadjusted relative to guide 13 by the operation of a spindle 20. Rollers16, 17 are retainedi'n adjusted positions by spring pawls 21, fitting innotches 22. The rollers 16, 17 accommodate a seriesof bands, each ofsaid rollers being provided with a finger-piece 23, whereby the'bandsmay be shifted as desired by imparting rotary motion to the rollers.

The printing bands l8, 19 are composed of rubber, the flexible metal andthe backing, all as hereinbefore described, each printing band beingpreferably of the endless form, and having the type characters a.

VVhile I have'shown and described the new rubber type as adapted for usein connection with the printing device of the-prior application, it isto be understood that the printing band mav be used in connection withordinary hand stamps employed for dating and numbering purposes, and,furthermore, that the composite fabric may be used for any other purposethan those herein mentioned.

When the invention is embodied in an endless band for printing purposes,the flexible metal layer B operates to wholly preclude any permanentstretching or elongation of the rubber type, for the reason that themetal layer is inelastic, although said layer is flexible in order thatthe fabric may yield or give when passing around the supporting wheelsand guides. The backing employed at the rear of the composite fabricenables the rubber to unite firmly to the textile fabric, and thus therubber layer and the perforated metal layer are so intimatelysecuredtogether that the parts will not separate. When rubber and perforatedmetal are-used to the exclusion of the fabric, or other backingmaterial, it is found that the rubber will pull awayfrom the metal, andthus the end less band will not act efiiciently, but by placing theperforated metal between layers of rubber and fabric, the rubber will beforced through the perforations in the flexible metal and unite with thematerial of the backing. As a result of the new construc tion the rubbermaterial passing through the perforations of the metal act to key themetal and rubber together, and the union of the rubber with the fabricis secured to the best advantage.

Having thus fully described the invention, what I claim as new, anddesire to secure by Letters Patent is 1 1. A new article of manufacturecomprising a' flexible non-stretching length or band of rubber typeunitary with a flexible fibrous backing and a flexible metal, saidflexible metal being positioned intermediate saidtype and the backingand operating to preclude permanent stretching of the rubber type. r

1 2. Anew article of manufacture comprising a nonstretching and'flexiblelength or band of rubber type unitary with a flexible fibrousbacking and a flexible perforated metal, said rubber type being keyed tosaid perforated metal. 3. A newarticle of manufacture embodying aflexiblenon-stretching length or band comprising a flexible rubber layerprovided with printing characters,'a flexible backing composed of fabricand a perforated layer of flexible metal positioned intermediate saidrubber layer and the backing.

4. As a new article of manufacture an endless flexible non-stretchingprinting band embodying a layer of rubber type, a flexible metal layeradjoining said type layer, and a backing of fabric adjoining the metalband,

the said layers and backing being unitary.

5. Anew article of manufacture comprising a band of rubber type, 'aperforated metal band, and afabri'c adjoining said metal band andsecured to the band of type through the perforations in the metal band.

6. ,As a new article of manufacture, a composite flexible printing bandcomprising an endless member composed of rubber and formed with printingcharacters. on its exposed face, an endless backingcomposed of fabric,and a third member composed of an endless piece of perforated metalpositioned intermediate the rubber member and the fabric backing memberand unitary therewith so as to attain the necessary adhe sion betweenthe rubber and the fabric, said interposed metal member operating topreclude stretching of the rubber with respect tothe fabric backing. 7.A new article of manufacture comprising a perforated flexible metalband, a band of fabric on one side thereof and a band of rubber type onthe opposite side and secured to the fabric through the perforations inthe metal band.

In testimony whereof I have signed my name to this specification in the;presence of two subscrlbing witnesses.
